Spy Wednesday in the context of "Cádiz"

Easter, also called Pasch (/pæsk/) or Pascha (Aramaic: פַּסְחָא , paskha; Greek: πάσχα, páskha) or Resurrection Sunday, is a Christian festival and cultural holiday commemorating the resurrection of Jesus from the dead, described in the New Testament as having occurred on the third day of his burial following his crucifixion by the Romans at Calvary c. 30 AD. It is the culmination of the Passion of Jesus, preceded by Lent (or Great Lent), a 40-day period of fasting, prayer, and penance.

Easter-observing Christians commonly refer to the last week of Lent, before Easter, as Holy Week, which in Western Christianity begins on Palm Sunday (marking the entrance of Jesus in Jerusalem), includes Spy Wednesday (on which the betrayal of Jesus is mourned), and contains the days of the Easter Triduum including Maundy Thursday, commemorating the Maundy and Last Supper, as well as Good Friday, commemorating the crucifixion and death of Jesus. In Eastern Christianity, the same events are commemorated with the names of days all starting with "Holy" or "Holy and Great", and Easter itself might be called Great and Holy Pascha. In both Western and Eastern Christianity, Eastertide—also known as the Easter or Paschal season—begins on Easter Sunday and continues for seven weeks, concluding on the 50th day, Pentecost Sunday. However, in Eastern Christianity, the leavetaking of the feast occurs on the 39th day, the eve of the Feast of the Ascension.

Holy Week (Koine Greek: Ἁγία καὶ Μεγάλη Ἑβδομάς, romanized: Hagía kaì Megálē Hebdomás, lit. 'Holy and Great Week') commemorates the seven days leading up to Easter. It begins with the commemoration of Christ's triumphal entry into Jerusalem on Palm Sunday, marks the betrayal of Jesus on Spy Wednesday (Holy Wednesday), climaxing with the commemoration of the Last Supper on Maundy Thursday (Holy Thursday) and the Passion of Jesus on Good Friday (Holy Friday). Holy Week concludes with Christ's death and descent into hell on Holy Saturday. For all Christian traditions, it is a moveable observance. In Eastern Christianity, which also calls it Great Week, it is the week following Great Lent and Lazarus Saturday, starting on the evening of Palm Sunday and concluding on the evening of Great Saturday. In Western Christianity, Holy Week is the sixth and last week of Lent, beginning with Palm Sunday and concluding on Holy Saturday.

Christians believe that Jesus rested in death from the ninth hour (3 pm) on Good Friday until just before dawn on Sunday morning, the day of his resurrection from death, known as Easter Sunday. However, in 1 Peter 3:19, there may be a clue as to a task Jesus performed during this period between death and resurrection: "By which also he went and preached unto the spirits in prison." This marks the beginning of the season of Eastertide, with its first week being known as Easter Week (or Bright Week).
